Anthropic Claude Cowork: Cowork Agent Lands on Mobile and Web

On Tuesday, Anthropic announced that Claude Cowork, its AI agent for performing digital tasks, is expanding beyond the desktop app: the agent now runs in the Claude smartphone app and in web browsers and can continue scheduled work without an active desktop session. Beta access will roll out first to Max subscribers.

What is new in Claude Cowork's mobile and web release?

Claude Cowork now operates on mobile and in browsers without a required desktop connection, and Anthropic is releasing the revamped Cowork as a beta to Max subscribers. The company showed a launch video where a user asks Cowork to pull data from email threads, Slack channels, meeting transcripts, and recent online chatter, then generate a reference document and a prewritten email for a business deal renewal. Previously, Cowork could perform those tasks only while a desktop session was active.

Anthropic plans to put the new Cowork beta behind its Max plan, which starts at $100 a month, and then move features to the Pro tier, which costs $20 a month. The rollout path for free users is unclear.

How does the mobile and web experience differ from the desktop app?

Mobile and web let users start, monitor, and approve Cowork tasks without keeping a laptop awake, but the desktop app still matters for local-machine capabilities. Anthropic once required a paired desktop session to keep tasks running; its description warned, "Your computer must be awake, and the app must be open for Claude to work on tasks." The Dispatch feature had allowed phone-to-desktop task requests but retained that limitation.

Decoder notes that the desktop app remains essential for features that require local file access. That includes reading and writing files in connected folders, local connectors and plugins, browser control through Claude in Chrome, and Computer Use where Claude clicks, types, and navigates directly on screen. The web version allows people who could not install the desktop app to try Cowork, but without those local capabilities. Anthropic is also unifying Chat and Cowork on desktop and web so projects and artifacts are available across platforms.

Anthropic released a usage report alongside the expansion. The company says more than 90 percent of Cowork usage is not software work, and the two biggest categories are "business process and operations" and "content creation and copywriting," which together make up roughly half of all usage.

Why it matters

The move pushes always-running, semiautonomous agents further into mainstream workflows by making them manageable from the device people carry most of the time. The expansion removes the practical friction that led some users to leave laptops open overnight to keep agent sessions alive. It also cements a pattern in which major players aim to embed agentic automation into chat interfaces rather than shipping separate apps: OpenClaw went viral at the beginning of 2026 and prompted OpenAI and Google to build their own always-on agents, while Anthropic has focused on usability with features like Claude Code and now Cowork on phones and browsers.

This shift raises usability and security trade-offs. The primary source notes Cowork previously exposed users to the risk of prompt injections and other security breaches. Making agents omnipresent on mobile increases attack surface and the importance of clear human-in-the-loop controls; Anthropic says the agent prompts the user when a human decision is required and nothing gets sent without review and approval.

What to watch

Watch for the beta trickle from Max to Pro subscribers and any announcements about free-user access. Also watch whether the unified Chat and Cowork home screen becomes the permanent interface and whether Anthropic removes the desktop-only restrictions on local file operations. A concrete calendar signal to track is the doubled Cowork usage limits extension, which Anthropic has pushed through August 5, and whether that cap is changed again as the beta widens.
